1-3-2 Performance Specifications
*4 A960 to A1471 and A10000 to A11535 cannot be accessed by CPU Bus Units, Special I/O Units, PTs, and Support Soft-
ware that do not specifically support the CJ2 CPU Units.
*5 Bits in the EM Area can be addressed either by bit or by word. These bits cannot be addressed by CPU Bus Units, Spe-
cial I/O Units, PTs, and Support Software that do not specifically support the CJ2 CPU Units.
*6 EM banks D to 18 cannot be accessed by CPU Bus Units, Special I/O Units, PTs, and Support Software that do not spe-
cifically support the CJ2 CPU Units.
*7 With CJ2H CPU Units with unit version 1.2 or later, force-setting/resetting bits in the EM Area is possible either for banks
that have been specified for automatic address allocation or for banks specified for the EM Area force-set/reset function.
With CJ2M CPU Units, force-setting/resetting bits in the EM Area is possible only for banks specified for the EM Area
force-set/reset function.

Index Registers IR0 to IR15
These are special registers for storing PLC memory addresses for indirect addressing. (Index Registers can be set
so that they are unique in each task or so that they are shared by all tasks.)
Cyclic Task Flag Area 128 flags
Memory Card 128 MB, 256 MB, or 512 MB
Operating Modes PROGRAM Mode: Programs are not executed. Preparations can be executed prior to program execution in this
mode.
MONITOR Mode: Programs are executed, and some operations, such as online editing, and changes to present
values in I/O memory, are enabled in this mode.
RUN Mode: Programs are executed. This is the normal operating mode.
Execution Mode Normal Mode
